Good point. In such a case, I think it would still be nice if at least trying to split the total change into a few separate commits, that builds upon each other. That way the commit log could be a good start to look at for someone who wants to understand the code base.

With the first commit being the specific commit from the PostgreSQL repo which they base their work on, i.e. that they forked from.
